Startups should aim to post between 20 and 50 classified ads monthly. This frequency ensures consistent presence across platforms while giving search engines fresh content to crawl and index regularly.

Yes, Google can index classified ads if they are published on high-authority platforms that do not block crawlers. Indexed ads appear in search results and can drive organic traffic and backlink value.
